JavaFx PieChart boundary colors

问题

When i build a pie chart in javafx, the boundary lines are always white.( I can set default slice colors with css). how can i set custom colors to boundary lines?

回答1:

Applying some css to the standard chart sample:

.chart-pie {
    -fx-border-color: derive(-fx-pie-color, -40%);
    -fx-border-width: 3px;

Here is the output with the css above applied:

Compared to the standard output with no additional CSS (using the default JavaFX 8 modena style):
